Tamarack Product Summary

Flush mount is a visually appealing, low profile, photovoltaic (PV) module installation system that significantly lowers PV module installation cost by allowing the installation professional to stock fewer parts and to com-plete the installation in less time.

Certified to meet local and International Building Codes when installed in accordance with this manual. The design load rating meets the minimum requirements of 10 PSF downward pressure, 5 PSF upward pressure and 5 PSF down-slope load. Module orientation may be portrait or landscape. Designed for use with most third-party roof attachments including Solar Roof Hooks, Quick Mount PV, Ironridge Flashfoot, S-5 Clamps, etc.

Class A Fire Rating per UL 1703 for steep roof slope applications when using Type 1 or Type 2 Listed Photovoltaic Modules. This is per Middle-ton fire test report 103427989MID-004.

ETL Listed to UL 2307 for bonding and grounding when installed in ac-cordance with this manual.

Rails, clamps, splices and mounting devices are UL2703 Listed for mounting flat-plate Photovoltaic Modules and Panels

Prepare for Installation

Plan the PV module layout that fits the roof and confirm that plans comply with local AHJ requirements.

The rails can be installed parallel or perpendicular to the roof rafters. Center the rails over the structural menbers as much as possible.

Leave enough room to work safely around the aray during the installation process. Some build-ing and fire codes require minimum clearances around PV module installations.

The length of the rails for each row in the installation will be equal to the total width of the modules plus 1/2-inch for each 50-50 clamp used between modules plus 2-inches total for end clamping. When using the channel end clamp, rails can be cut to the edge of the array.

Install proper roof mount flashings per the manufacturer’s instructions. The maximum allow-able spans between roof supports is 6 feet.

Attach Rail Mounts

Each Rail-Mount consists of two parts, a 5/16 inch bolt and a clamp extrusion. The rail adapters have been designed to interface with off-the-shelf mounting products that have vertical leveling slots. Our Rail Mounts work with most products that have 5/16 inch or 3/8 inch bolt slots. We also offer our own L foot for mounting to products that have a flat mounting surface, such as seam clamps, exposed beams or Quick Mount Q Blocks.

Install Rails

Rails are sold in convenient 84-inch and 126-inch lenths. This length is enough for two or three 60 cell or 72 cell modules with a width of up to 40.5 inches. Use a Tamarack bonding splice to connect each section of rail in a row.

If a cut section of rail is required for the installation, it must not be installed at the end of a row. Each section of rail at the end of a row must be supported by two mounts before being spliced. If a rail section has a splice and 3 roof mounts, the splice should be located within 1/3 rail span of the middle mount.

Rail mounting is simple and easy. The Rail Adapter clamps to the two feet on the bottom of the rail. There is never any drilling, and parts can be brought on the roof fully assembled and ready to be installed. Rail Adapters may be installed anywhere on the rails, including at splices and they will not interfere with module mount-ing clamps.

Simply position the adapter into the two feet on the bottom of the rail, and tighten the bolt slightly. Leave the bolt slightly lose to allow leveling of the rails in the next step.


7

Leveling Rails

Start by leveling the bottom rail of the array first. Set the Rail Adapters near the middle of the leveling range and adjust as necessary to have visually level rails. Tighten the attachment bolts to the specified torque when they are aligned. Level the top rail of the array in the same manner.

If there are multiple rows of rails in the array, use a string level or straight edge to help adjust the remaining rows to be level with the top and bottom rails. It is also possible to visually align rails in the middle of the array.

Tighten all hardware to the specified torque.

Grounding

Tamarack rails and PV modules are bonded by 50-50 Module Clamps and bonding splices.The 50-50 clamps acheive bonding to the module frames by stainless-steel pins in the clamping surface of the clamp tops, which penetrate module frame coating. The rails and channel nuts are bonded because of the conductive surface of the mill finish aluminum used in the rail con-struction.

SolarEdge Optimizers and Enphase Microinverters are bonded to the rail with the Tamarack MPLE adapters.

Bonding Method 1: Rail LugUse a Ground Clamp to bond a ground conductor to a rail.

Bonding Method 2 (Optional): Frame LugUse a module ground lug to bond a module frame to a ground conductor. The resulting system is bonded primarily through the module frames. This method may not be acceptable to all building inspectors. This lug is not included in the kit.

Module Level Power Electronics

Use the Tamarack MLPE Rail Adapter to attach Enphase microin-verters or SolarEdge Optimizers to the rails.The large flat washer is installed between the mounting plate of the MLPE and the top of the rail. Tighten the bolt to 12 ft.-lb. with a torque wrench and a 1/2-inch socket.

Wire Management

Place electrical conductors and connectors at the bottom of the rail channels.

Install the wire protection clips where necessary to keep wires in the channels.

When using 1.6 inch rail, it is possible to damage connectors or large bundles of wire when 50-50 bolts are tightened. Position con-nectors and bundles appropriately to prevent risk of ground faults.

NOTE

These kits may have extra parts that will not be needed in some situations


11

Module Installation

Start module installation at one end of the rails. If there are multiple rows, start on the bottom row. Install a 50-50 clamp at the end of each rail with the side of the clamp with 2 bonding pins on the module frame. Push the channel nut into the rail. The integrated spring assembly will hold the clamp in place.

Place the first module onto the rails so that it is centered over the rails. Make sure the module is touching the inside edge of the clamps and tighten the clamps with a 1/2” socket.

Install 50-50 Clamps in each rail on the other side of the first module. The springs will hold the clamps in place prior to tightening. Place the second module on the rails, align it with the first module, and push in against the clamps. Tighten the clamps to fully secure the module.

Install the remaining modules and clamps on the rails in the same manner, aligning the corners of the modules.

On the outside edge of the last module, install the clamps so that the side with the two stainless-steel pins is on the module frame. Tighten all bolts to the specified torque.


12

Do a final check to be sure that all installation hardware on the array is properly tightened to 12 ft. lbs.

Channel End Clamps

Channel End Clamps may be used in place of the 50-50 clamps at the ends of rails. Channel Clamps secure the module frame from below and allow the rails to be cut flush to the edge of the array for a clean look.

Insert channel end clamp in the rail. The module must be lifted slightly to slide the clamp under the frame. Allow the module to rest on the rail again and slide the clamp back toward the end of the module until it is flush with the outside end of the module frame and tighten lightly. Feel under the array to check that the clamp is clamping the module flange securely, then tight-en to 12 ft. lbs.

End Caps

Place an end cap at the end of each rail to inprove the look of the system. Drain holes on the bottom of the end caps ensure that water does not accumulate in the rails.
